Wang, C. Kao] The effect of AlCl3 on the antioxidant system of rice roots and the role of applied antioxidants ascorbic acid (AsA) and glutathione (GSH) in AlCl3-inhibited growth of rice roots were investigated. AlCl3 treatment resulted in a rapid inhibition of root growth but had no effect on lipid peroxidation and antioxidative enzyme activities in rice roots. AlCl3 treatment resulted in lower content of H2O2, AsA, and GSH than in controls. Exogenous AsA or GSH counteracted growth inhibition of rice roots induced by AlCl3. AlCl3 treatment increased syringaldazine peroxidase (SPOX) activities and lignin content in rice roots. Exogenous AsA or GSH prevented the decrease in H2O2 content and the increase in SPOX activities and lignin content in rice roots caused by AlCl3. Results suggest that lignification induced by low AsA or GSH content may explain the mechanism of Al-inhibited growth of rice roots.
